Description

Technical Field

[0001] This utility model relates to the field of nail assembly technology, specifically to a plastic strip and its connection structure with the nail. Background Technology

[0002] In the field of modern fastening technology, nails, with their core advantages of rapid firing and precise fixing when used in conjunction with nail guns, have achieved efficient fastening of various media such as walls, floors, steel plates, and wood panels in scenarios such as building decoration, furniture manufacturing, and industrial assembly. Their ease of operation, reliable fixing, and cost-saving characteristics make them an indispensable fastening component in various assembly scenarios.

[0003] With the expansion of the market and the increasing demand for precision, the industry has designed a combination structure of nails and plastic arrangement. This combination structure not only facilitates storage, transportation and assembly, but also adapts to the continuous nail supply requirements of automated nail guns, greatly improving the efficiency of batch fastening operations. However, existing plastic strips generally use a round hole structure that matches the nail shank, such as the strip for injection nails disclosed in patent document CN202825733U. During nail assembly, positioning and fixing are achieved through the surface contact between the nail shank 3 and the inner wall of the round hole 4. Figure 6 As shown. However, due to the inherent characteristic of the nail's structure—the arc-shaped transition between the nail shank and the nail head and tip at both ends—coupled with quality variations during nail production, the dimensions of the upper and lower ends of the nail shank are inconsistent. This results in a significant difference in the interference fit between the fixing holes on the upper and lower ends of the plastic strip and the nail shank when the nail is assembled into the round hole on the plastic strip. This uneven interference fit will cause the plastic strip to exhibit the following shape along its length after the nail is assembled: Figure 7 The obvious bending deformation is shown. This deformation not only affects the stability of the nail bar during storage and transportation (e.g., bent bars are prone to stacking and jamming, or cause nail misalignment), but also negatively impacts subsequent assembly operations. For example, during automated nail gun feeding, bent bars may not pass smoothly through the feeding channel, causing feeding jams. Or, even if feeding is successful, bent bars can cause deviations in the nail firing angle, reducing the accuracy of the fastening position, and may even affect the fastening strength due to tilted nail firing, increasing potential assembly quality issues. In addition, to ensure the stability and reliability of the nails on the plastic strip, the nails are usually fixed in the round hole by interference fit. However, since the inner wall of the round hole is close to the outer wall of the nail rod, there is no redundant interference between the round hole and the nail rod. When the interference fit is large, the plastic strip is prone to cracking.

[0004] Therefore, it is necessary to develop a new technology that provides redundant interference after assembling the nail gun and can prevent the plastic strip from deforming in the length direction in order to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model addresses the shortcomings and defects of the existing technology by proposing a plastic strip and its connection structure with the nail. The aim is to improve the circular holes on the existing plastic strip by replacing them with diamond-shaped holes, changing the surface contact assembly method between the nail rod and the existing circular holes to a line contact assembly method. This not only gives the diamond-shaped holes a redundant interference fit after assembling the nail, allowing them to withstand a larger interference fit without cracking, but also reduces the deformation of the plastic strip in the length direction, changing the direction of deformation and thus effectively preventing the plastic strip from bending and deforming in the length direction.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A plastic strip includes multiple fasteners for assembling nails, each fastener having a diamond-shaped hole for forming a line contact assembly structure with the nail shaft.

[0007] The aforementioned line contact assembly structure refers to the following: after the nail rod is assembled into the diamond-shaped hole, the outer wall surface of the nail rod forms line contact with the four inner sides of the diamond-shaped hole.

[0008] The fastener has two diamond-shaped holes, which are arranged at vertical intervals.

[0009] The four corners of the rhomboid hole have an arc-shaped transition.

[0010] A connection structure between a plastic strip and a nail is disclosed. The plastic strip includes multiple fasteners for assembling the nail, each fastener having a diamond-shaped hole. The nail is interference-fitted into the diamond-shaped hole, and the diamond-shaped hole and the nail shaft form a line contact assembly structure.

[0011] The aforementioned line contact assembly structure refers to the following: after the nail is assembled into the diamond-shaped hole, the outer wall surface of the nail shank forms line contact with the four inner sides of the diamond-shaped hole.

[0012] The fastener has two diamond-shaped holes, which are arranged at an interval between the top and bottom. The upper and lower parts of the nail rod are fixed in the two diamond-shaped holes respectively.

[0013] The four corners of the rhomboid hole have an arc-shaped transition.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The key innovation of this utility model lies in improving the existing round holes on plastic strips to diamond-shaped holes, and changing the surface contact assembly method between the nail shank and the existing round hole to a line contact assembly method. Based on this specific innovative improvement, after the nail is assembled into the diamond-shaped hole, the nail shank and the hole have a line contact structure, which can reduce the deformation in the length direction of the plastic strip, thereby changing the direction of deformation of the plastic strip and effectively preventing bending deformation in the length direction, thus improving the quality of the plastic nail. In addition, besides the line contact area between the diamond-shaped hole and the nail shank, there is also a redundant area inside the diamond-shaped hole that is not filled by the nail shank. This allows the diamond-shaped hole to withstand a larger interference fit without cracking, which is beneficial for assembling nails of more sizes and has a wider range of applications.

[0015] 2. The present invention uses diamond-shaped holes arranged at intervals, which is beneficial to achieve stable and reliable fixation of the nails on the plastic strip. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] Example 1 like Figures 1-4 As shown, this embodiment provides a plastic strip, which includes multiple fasteners 1 for assembling nails, with adjacent fasteners 1 connected by connecting ribs. Crucially, each fastener 1 has a diamond-shaped hole 2 arranged along its axis, allowing each fastener 1 to form a line contact assembly structure with the nail shank 3 through the diamond-shaped hole 2.

[0020] Specifically, the aforementioned line contact assembly structure refers to the line contact structure in which the outer wall surface of the nail rod 3 intersects with the four inner sides of the rhomboid hole 2 after the nail rod 3 is assembled into the rhomboid hole 2.

[0021] In this embodiment, the number of diamond-shaped holes 2 on the fixing member 1 is two, and they are arranged at intervals. Each fixing member 1 can fix the nail through the diamond-shaped holes 2 arranged at intervals, so that the nail is more stable and reliable on the plastic strip.

[0022] In this embodiment, each rhomboid hole 2 has an arc-shaped transition at its four corners.

[0023] It should be noted that the shape of the fastener 1 is not limited in this embodiment. It can adopt an existing conventional shape, preferably one that can meet and match the track of the corresponding nail gun.

[0024] Figure 4 , Figure 5 The structure of the nail being assembled into the diamond-shaped hole 2 of the plastic strip is shown, based on Figure 4 , Figure 5 It is known that the outer wall surface of the nail rod 3 and the four inner sides of the rhomboid hole 2 form a line contact structure with intersecting surfaces. This structure reduces the deformation of the plastic strip along its length, changing the direction of deformation and effectively preventing bending deformation of the plastic strip along its length, thus improving the quality of the plastic nail. In addition to the line contact area, the rhomboid hole 2 also has a redundant area not filled by the nail rod 3. This allows the rhomboid hole 2 to withstand a larger interference fit without cracking, facilitating the assembly of nails of various sizes.

The plastic strip includes multiple fasteners 1 for assembling the nail, and adjacent fasteners 1 are connected by connecting ribs. Crucially, each fastener 1 has a diamond-shaped hole 2, in which the nail is interference-fitted and formed with the nail shaft 3, creating a line contact assembly structure.

[0026] Specifically, the aforementioned line contact assembly structure refers to a line contact structure in which the outer wall surface of the nail rod 3 intersects with the four inner sides of the rhomboid hole 2 after the nail is assembled into the rhomboid hole 2.

[0027] In this embodiment, the fastener 1 has two diamond-shaped holes 2, arranged at vertical intervals, and the upper and lower parts of the nail rod 3 are fixed in the two diamond-shaped holes 2 respectively. Each fastener 1 can fix the nail through the diamond-shaped holes 2 arranged vertically, making the nail more stable and reliable on the plastic strip.

[0028] In this embodiment, each rhomboid hole 2 has an arc-shaped transition at its four corners.

[0029] It should be noted that the shape of the fastener 1 is not limited in this embodiment. It can adopt an existing conventional shape, preferably one that can meet and match the track of the corresponding nail gun.
